Equipped with 3-channel control and Spektrum™ 2.4GHz radio technology, the Radian can be flown without the worry or risk of interference. Although a powerful 480 brushless motor enables initial launch, the propeller soon folds back to reduce drag, freeing the plane to utilize thermals of air to remain aloft, instead of batteries. That means flight times for this quiet and eco-friendly alternative are much longer than they are with traditional electric aircraft, making a relaxing day in the great outdoors even better.

Like all of ParkZone’s innovative and high-quality aircraft, the Radian looks great right out of the box and provides pilots with the control and reliability they seek in a park flyer. The plane’s large 2-meter wingspan and elliptical dihedral design improve flight performance and visibility from the ground, while plug-in wings provide for easy transportation and storage.

Not only does the Radian’s lightweight Z-Foam™ construction offer the perfect balance of weight and durability, it also makes repairs simple and quick. Since everything needed to get the Radian airborne is included inside, you are only minutes away from the ultimate soaring adventure.

Wingspan: 78.7 in (2 m)

Overall Length: 44.7 in (1137mm)

Flying Weight: 30 oz (830 g)

Motor Size: 480 brushless outrunner, 960Kv

Radio: Spektrum 2.4GHz DX5e with AR600 full range receiver (included)(Originally included the AR500)

The Radian was perfect! It went together easy and it balanced perfect . I covered the bottom surface of the wings with clear packing tape first and did the same to the aft fuselage to stiffen up the tail. First flight went perfect with the trim being right on. I checked the trim with the motor off first then launched it with 1/4 to 1/2 throttle. I love it! I actually caught it in my hand the first two flights. Mind you, I have not flown an R/C for around five years. The performance is great and the damn thing does not want to come down. The battery will last forever because it only needs to be on for seconds at a time and it goes up on anything. This is a wonderful toy and I recommend it to everyone. Oh, the power is incredible! It will climb straight up forever! I believe it can be a wonderful plane if it had half as much power. Overall, I love the Radiant.

Learned to fly in one afternoon

Radian RTF is my first plane. I did a simulator for a couple hours then flew it with an experienced friend for two hours. Unbelievably easy to fly and learn to maneuver. I did a loop, landed a dozen times smoothly with minimal assist. I went home and flew alone off the cliff that my home is perched on. Landings were tough because of the terrain but no damage despite nosing into a rock once. Very little motor use needed when there is a little wind or thermals. Great plane!

Radian

I bought the Radian and I am a novice pilot and have flown some other other EP 2 meter sailplanes and they just didn't seem to float but would sink but the Radian goes up well on only half throttle and it floats when you turn off the power. You can tell when your in lift because this plane is light and reponds well to the air currents. I am using oi to get better at finding lifts and helping me become a better sailplane pilot. I have a blast with it and can easly fly an hour on one battery. I highly recommed the Radian

Parkzone Radian Sailplane, a winner

Parkzone did a nice job on the Radian, flights are lengthy, brushless motor takes her up easily at only half throttle, its a true floater, flew the EasyStar nice trainer, but he Radian is simply great, responds to lighter lift, and as a bonus will handle over 10 MPH winds.. Suggest flush or slightest downtrim on the elevator no up required at all, keep the nose level on launch and your in for a treat..flight times are near an hour with zero lift, a wonderful flyer, you won't regret this one, fantastic..BEST WARREN ...
